wheels of the vehicle. Y The brake thus ap-l plied will prevent what iscommonly known as skidding and will enable 'the operator of the vehicleto have more and better control over his vehicle. i

It may also be employed ing steep grades, itis necessary to stop thevehicle'and will thereby secure safe and certain protection againstslipping back.

In the drawing, n

' Figure l is a plan view of a motor vehicle frame illustrating myimproved braking device, and i l, l

Fig. 2 is a longitudinal sectional view of the motor vehicle frameembodying my invention. Y

Referring now more p companying drawing, the brake is mounted andsupported on a vehicle frame l by means of a crank shaft 2 rigidlyVengaging the vehicle frame and brackets 3, The brakeis composed of afoot 4, 4, ofsuitablestruci 'ture to withstand sudden and forciblecontact with the groundwhile the vehicle is,

moving at any speed and itsunder surface is" when, in ascend-varticularly to the f ac-l provided with teeth 5 or'otlierwise con- .I i

structed to create a high degree-of resistance when engaging the ground.

A brake foot. 4, 4, is pivotally connected to 40 I a bar 7,'and'thebar'is pivotally connected to v a crank 8, of the crank shaft.- The bar7, may

besupported and guided .by a bracket 9, 9, mounted onthe rear. aXlehousing l0, and the bracket 9, 9, may be providedwith a channel 11,11,inclined downwardly towards the rear of the vehicle to loosely engagethe `bar. and a -K portion of the upperwall ofthe channel is cut away asshown at l2, so that when the brakingmernber is out of act-ion thebarmay 50. rest in horizontal position. The brake may be operated by abrake lever 13, as shown and yis connected to the crankshaft by a rod14, and arm 15. v l

.VVhatIclaim isz y v 55 In combination with a motor vehicle, a brakingmember comprising a foot, and havingV its lower surface toothed forfrictional engagement with the ground, a crankshaft mounted onthevehicle frame having a crank, l

a'bar to lwhich the foot'is connected and which is connected to thecrank of the crank shaft, a bracket mounted on the rear aile housing andhaving an opening through whicha bar'is free to slide longitudinally and65' rock therein, and a brakelever.` with a rod 1 pivotally connectedthereto and an arm pivff otally connectedto `the rod and rigidlyconnected to the crank shaft. l
